Abstract
AbstractA new, unobtrusive method for liquid‐liquid two‐phase flow data collection was proved to be reliable in this research. Drop size distributions and concentration profiles were determined for a dilute water‐inkerosene system under horizontal straight pipe flow using this technique, and the Segev model for predicting concentration profiles was tested with the data collected here.The drop size distributions were found to follow a Rosin‐Rammler function for a limited droplet diameter range, and the average value of the exponent in the Rosin‐Rammler equation was determined to be 2.0. The velocity where the flow regime makes a transition from stratified to adequately dispersed flow was found to be between 2.0 and 2.2 m/s. Concentration profiles predicted by the Segev model were in general agreement with the profiles determined in this work, and using the proper choice of model parameters noticeably improves the model predictions.
